WINDOW.

SPECIFICATION forming part of Letters Patent No. 582,141, dated May 4,1897. Application filed March 11, 1896. Serial No. 582,773. (No model.)

To all whom 2123 may concern..-

Be it known that we, WALTER V. RICH ARDS and ISAIAH BLOCH, citizens ofthe United States, residing at Philadelphia, in'

the county of Philadelphia and State of Pennsylvania, have inventedcertain new and useful Improvements in Windows, of which the followingis a specification.

Our invention relates to a new and useful to improvement in windows, andhas for its object to so construct a window as to permit the sashesthereof to be swung upon horizon tal pivots without interfering with theusual method of raising and lowering said sashes, I5 and to so bringabout this result as to leave the window as weather and dust proof asusual, or more so.

lVith these ends in View our invention consists in the details ofconstruction and combination of elements hereinafter set forth, and thenspecifically designated by the claim. In order that those skilled in theart to which this invention appertains may under stand how to make anduse the same, we will describe its construction and operation in detail,referring by numbers to the accompanying drawings, forminga part of thisspecifica tion, and in which- Figure l isaperspective of a window,showing one of its sashes partly swung open; Fig. 2, an elevation of onesash, the guide-grooves being in section and a portion of the side railbroken away to show 1n ore clearly the method of attaching the sash tothe sliding shoe; Fig. 5 3, a central vertical section of the window,showing the sashes in their normal position in full lines and in dottedlines in the positions they may assume when swung upon their pivots;Fig. 4, a section at the line a 03 of Fig. 3; Fig. 5, an enlargedsectional elevation showing the guide-grooves, one of the sashes slidingtherein, and a portion of a sash pivoted to said shoe; Fig. 6, anenlarged elevation of one of the locking-plates, the lock- 5 ing-pin andguide-stri p being in section; and Fig. 7, a section at the line y 'y ofFig. 6.

Similar numbers denote like parts in the several views of the drawings.

In carrying out our invention we provide the ordinary window frame 1with a molding 2 upon each side thereof, whichis preferably constructedof a single board having two grooves 3 and at for each sash, and theusual pulleys 5 are so placed as to aline with the grooves 4, in whichlatter run the weight-ropes 6 for balancing the sashes, and the outerend of each of these ropes is attached to a shoe 7, adapted to slidewithin the grooves at. Each of the sashes 8 and 9 is pivoted to two ofthe shoes, which run in opposite grooves, by means of the trunnions 10,projecting from the plates 11, which in turn are secured to the edges ofthe sash by suitable screws and countersunk so as to be flush with thesurfaces of said edges, in order that they may not interfere with themovements of said sash. By this arrangement it will be seen that eitherof the sashes may be swung upon its trunnions and caused to assume anyangle, as clearly shown in Figs. 1 and 3.

It is to be noted that each of the sashes is guided laterally by theouter surfaces of the moldings 2 and has no connection with the groovesin said moldings, except by its attachment to the shoes, and is thusleft free to swing upon its trunnions. To hold the sashes in a verticalposition and cause them to travel longitudinally of the frame, each isprovided with two guide-strips 12, which in the construction here shownlie upon the front surface of the side rails of the sashes and parallelwith the edges thereof in such man-' ner that when in their normalpositions they project within the grooves 3, thereby preventing thesashes from swinging upon their trunnions and at the same time servingthe purposes of weathenstrips to prevent the passage of air or dust.These strips are attached to the sashes by means of headed pins 13,which project from the plates 14, attached to and countersunk in theinner surfaces of said strips, the pins passing through inverted-U-shaped grooves 15, formed in the lockingplates 16, which latter aresecured to and countersunk in the surfaces of the side sashrails, theheads of the pins engaging with the rear side of the plates, so as toprevent their withdrawal, as readily understood by reference to Figs. 6and 7. In order to insert the headed pins within the locking-grooves 15,one wall of each of said grooves is broken by a notch 17 of sufficientsize to permit the free passage of the heads of said pins, so that inattaching a guide-strip to a sash it is only necessary to aline theheads of the pins with the notches 17, when the former may be passedthrough said notches into engagement with the slots, when by moving thepins to one end or the other of the slots they will be held againstdisplacement. From this it will be seen that a guide-strip may be lockedinto its groove by placing the pins in the end of said grooves nearestthe molding, from which position it cannot be accidentally displaced;but when it is desired to withdraw the guidestrip from its groove it isonly necessary to slightly lift the same, thereby carrying the pins overthe highest points in the grooves and again downward to the oppositeends of said grooves, where they will be retained, thus freeing thestrip from the molding, and when this has been done in connection withthe two strips of a sash the latter will be free to swing upon itstrunnions, as above described. It is to be noted that each strip isprovided with two pins and each side rail of a sash with a correspondingnumber of locking-plates. For the accommodation of the heads of the pinswhen passed through the locking-plates recesses 18 are formed back ofeach plate, as clearly shown in Fig. 7. The upper ends of the shoes arepreferably reduced in thickness sidewise, so as to permit the attachmentof the weight-ropes without interfering with the free travel of the saidshoes within their respective grooves.

In practice the sashes of a window constructed in accordance with ourimprovement when locked longitudinally by the guidestrips maybe raisedand lowered in the same manner as the sashes of an ordinary window, andthe joints between said sashes and the window-frame are asweather-tight, if not more so, as has heretofore been the case, and yetwhen it is desired to clean the glass of a sash this is greatlyfacilitated by moving the guide-strips inward, as before described, byswinging the sash upon its trunnions, in which case access is had toboth sides of the glass from the inside of the room, and another greatadvantage had by our construction is. that the ventilation of a room ismade more complete in that both sashes of a window may be so swung as toleave a clear space practically the full size of the opening in thewindowframe.

While we have shown the guide-strips arranged upon the outer surfaces ofthe side rails of the sashes, it is obvious that they might be set ingrooves formed in the edges of said rails, or that they might bearranged upon the rear surfaces thereof, or that we might employ morethan one of said strips for each rail, the gist of our invention restingin the broad idea of arranging each sash of a window so as to be guidedbetween the outer surfaces of the molding or sides of the casin g and toso connect them to said molding as to permit them to swing upon suitabletrunnions, and provide means for locking them longitudinally with theframe and providing for the unlocking thereof, whereby they will be freeto swing.

Having thus fully described our invention, what we claim as new anduseful is- In combination, a window-frame having grooves formed in theside ways thereof, a sash adapted to slide vertically between said ways,a shoe pivoted to the middle of each side of the sash, said shoesadapted to slide in the grooves of the frame, means for slidablysupporting the shoes, guide-strips slid able in the slots of the frame,plates provided with headed pins secured on the guide-strips, platessecured on the sashes having inverted- U-shaped slots with enlargementsin their upper parts in which said headed pins are adapted to slide,whereby the guide-strips are adjustably and removably secured to thesash, as and for the purpose described.

In testimony whereof we have hereunto affixed our signatures in thepresence of two subscribing witnesses.
